Tomsk scientists created fast sensors based on organic molecules
At the heart of the multilayered sensor is a nanoscale lattice made of polymer. A thin gold film is deposited on the lattice. The surface of the film is then modified with organic compounds that would interact with the molecules of the substance sought. Some compounds can selectively «capture» heavy metals, others — foreign DNA, some interact well with fatty molecules in the blood.
Such devices would be useful not only for the study of harmful substances, but also for the search for infectious diseases in places crowded with people, Postnikov explained.
